The name of the element with given atomic numbers are:

X = 2 = Helium

Y = 6 = Carbon

Z = 10 = Neon

When these elements are located in periodic table,

Helium (X) is present in 18th group and 1st period.

Carbon (Y)is present in 14th group and 2nd period.

Neon (Z) is present in 18th group and 2nd period.

From the above data, it can be inferred that elements such as Helium (X) and Neon (Z) belong to same group (18), whereas elements such as Carbon (Y) and Neon (Z) belong to same period (2).
